Aquatic invertebrate research

A preliminary survey and analysis of the spatial distribution of aquatic invertebrates in the Okavango Delta by Dr Helen F. Dallas and HOORC researcher and BIOKAVANGO team member Dr Belda Mosepele, has been published in a recent issue of the African Journal of Aquatic Science. Differences in macroinvertebrate assemblages were observed amongst different habitat types, with differences most pronounced between the deltaic habitats and isolated seasonally-flooded pools and temporary rain-filled pools. The researchers found the highest number of taxa in marginal vegetation in channels and lagoons, the fewest in sediment. You can find the article in HOORC's Library.
